Features
- Deleter command to recursively delete all related nodes, media, and files.
- Generate thumbnails command to re-derive thumbnails for nodes.
- Null child weight command to identify and update nodes with a mix of null and integer values in field_weight.
- Re-derive command to re-derive all derivatives for a set of nodes.
- A user wrapper to replace the legacy --user drush wrapper to support user in drush commands.
Requirements
This module requires the following modules/libraries:
Installation
Install as usual, see this for further information.
Usage
Deleter
drush islandora_drush_utils:delete-recursively -vvv --dry-run --empty 7,11 --user=islandora
Given a comma-separated list of nodes to target, this command performs a breadth-first search to find all descendent nodes and deletes them, including their related media, and marks files related to media as "temporary" such that they become eligible for garbage collection by Drupal.
Generate thumbnails
drush islandora_drush_utils:rederive_thumbnails --model=Image -vvv --nids=7,11 --user=islandora
Given a comma-separated list of nodes to target, this command will re-generate thumbnails for the target model. A file containing comma-separated nids can also be provided as input.
Re-derive
drush islandora_drush_utils:rederive -vvv --user=islandora
This command re-generates all derivatives on the website. It is possible to define which "media use" term should be used as the source for derivative generation. This defaults to Original file
Null child weight
drush islandora_drush_utils:null-child-weight-updater --verbose --dry-run 10 --user=islandora
This command identifies and updates nodes that have a mix of null and integer values in field_weight.
Queue runner
We have taken to use queue:run more; however, it does not natively have protections like running batches do, to occasionally re-fork to reduce memory usage due to Drupal's use of static caching.
This command allows the specification of some options with which to run a queue to completion:
--time-per-iteration: The amount of time we will requestqueue:runto run, in seconds. Defaults to 300.--items-per-iteration: The number of items to requestqueue:runto process. Defaults to 100.
Otherwise, this is intended to be just be a slightly safer (in terms of memory usage) alternative to queue:run.
This command is just islandora_drush_utils:queue:run, and might be invoked with something like:
drush islandora_drush_utils:queue:run {queue_id}
where {queue_id} is the ID/name of one of the queues as might be returned from queue:list (or otherwise defined as the ID of a @QueueWorker plugin).
SEC-873 Remedy
SEC-873 is an internal issue dealing with repercussions of https://www.drupal.org/project/views_bulk_edit/issues/3084329 .
With this issue, replacing or adding paragraphs values to paragraph fields using Views Bulk Operations "modify fields" operation could lead to the same paragraph entity/ID being unexpectedly used across multiple parent entities. This can then lead to issues attempting to individually edit any of these entities, such as values from different paragraph revisions leaking to other entities referencing the same paragraph ID.
At the moment, this d.o issue is still open; however, there are patches on it which appear to work (though there may be other issues if combining with allowing the creation of new taxonomy terms inside of the paragraph; however, such should be able to be worked-around by creating such terms first, separately).
The process here creates new paragraph entities where it is detected that a paragraph is being shared across multiple parent entities, such that future edits the particular items should work as expected.
There are a few related commands:
islandora_drush_utils:sec-873:get-current: Dumps CSV to stdout which can be consumed by the:repairand/or:repair:enqueuecommands, identifying what paragraphs are referenced across which entities in current/default revisions.islandora_drush_utils:sec-873:get-revisions: Similar to:get-current, dumps similar CSV to stdout across ALL revisions, including the revision ID alongside entity IDs. Intended more for informative purposes.islandora_drush_utils:sec-873:repair: Wraps the[...]:enqueueand[...]:batchcommands together, for convenience.islandora_drush_utils:sec-873:repair:enqueue: Consume CSV to populate queue to be processed.islandora_drush_utils:sec-873:repair:batch: Process the populated queue.
User wrapper
--user=1
Before Drush 9, there was a "--user" option that could be used to run commands as other users. Here, a new "@islandora_drush_utils-user-wrap" annotation is provided, which can be used to allow the --user option in commands.
